The Phidget C API
A Sample Phidget Program Using the C API
Overview
Most software created for Phidgets is written in high level
languages such as Java or a .NET language. Such languages have
powerful features and drastically simplify the creation of a GUI.
In some instances however it may be necessary to create
programs in C. C code has the advantage that it can be targeted
to run on a wide variety of operating systems and architectures.
The C API is also useful for creating custom libraries for other
programming languages that are not explicitly supported by
Phidgets Inc. The C library (Phidget21.dll or the outdated
Phidget.dll) is a base library and is used in all other Phidget
libraries (.NET, COM, etc). Programs using the C API need only
the Phidget21.dll (or Phidget.dll) to be installed on the computer
running them.
Programming Requirements
To create a C program, two files provided by Phidgets Inc. must
be used.
Phidget21.h - This header file provides the Phidget functions.
It can be found in the Examples.zip/C++ directory.
Examples.zip can be downloaded from the Phidget web
site under…
